    • An operation history display device of a numerical control apparatus by which a fault causing factor can be easily specified. Key input means outputs the key signal of an operation key depressed by an operator to input a command to the numerical control apparatus. Change detection means detects a change of an output signal and outputs the signal to which the change is caused. Operation history control means stores the signal name and the like of the signal to which the change is caused to a history buffer together with a present time output from a timer as history data. Thereafter, display control means displays the history data stored in the history buffer on a display unit in response to a predetermined operation performed by the operator.

    • There is provided a numerical control unit having a processor (102a), a control program memory (102b), a memory (102c) for storing files, and input means (102d) for accessing the files. The processor (102a), in accordance with the control program, processes externally entered control data to numerically control a machine connected thereto. The arrangement is such that the name of a file to be protected is stored in the memory (102c) of the numerical control unit and, the name of an object file is compared with the protected file name in the memory (102c), when a modification command and the name of the object file are entered from the input means (102d). Processing for modifying the file is executed, on the condition that there is a processing confirmation input from the input means (102d), when the object is a file protected file.
    • 提供了具有处理器(102a),控制程序存储器(102b),用于存储文件的存储器(102c)和用于访问文件的输入装置(102d)的数字控制单元。 根据控制程序,处理器(102a)处理外部输入的控制数据,以数字控制连接到其上的机器。 该安排使得要保护的文件的名称存储在数字控制单元的存储器(102c)中,并且将目标文件的名称与存储器(102c)中的受保护文件名进行比较,当 修改命令和目标文件的名称从输入装置(102d)输入。 当对象是受文件保护的文件时,在输入装置(102d)存在来自处理确认输入的条件下执行用于修改文件的处理。

    • An electrode retraction control system of an electric discharge machine for rapidly retracting an electrode from a workpiece, in which the retraction velocity and readvance velocity of an electrode (EP) moving relative to a workpiece (WK) are set to a velocity obtained by multiplying, by a fixed multiplication factor (a, k), a velocity decided on the basis of a gap sensing voltage (Vd) corresponding to the magnitude of a gap between the workpiece (WK) and the electrode (EP), the velocity being held constant during retraction and readvance. Machining efficiency is advanced by raising the retraction velocity and readvance velocity of the electrode (EP).
